When you look at that graph, and, indeed, today's, you'll notice that the peak moments coincide with low wind speeds. Winds are very strong in spring afternoons and I believe they blow a lot of the pollution away. When the wind dies down at night, the air fills up with pollution again. From diesel trucks, certainly, but construction, too. And agricultural stalk burning.
What puzzles me is that the humidity, which reaches 100% at night, doesn't precipitate the pollution. I thought it should?
Anyway, high AQI rates are common for Kunming in spring. But that doesn't mean it isn't utterly disgusting. We should all be aware that we're slowly being killed here.
Infrastructure money continues to pour into Kunming
发布者I believe that being part of WTO means that you cannot tax the hell out of private cars.
Look at Vietnam: a two-wheeled paradise until WTO forces them to lower tax on imported cars, which means everyone is going to start driving their cars which means that paradise is going to hell in a handbasket.
So don't blame China alone - blame all members of WTO, the car-producing ones first.
Kunming's former party boss charged with corruption
发布者Well here's nothing shocking.
People involved in major (and seemingly unnecessary) construction projects often have dirt on their hands.
- The metro, gobbling up eight years of the city's annual revenue, is IMHO unnecessary (reducing car culture, or an above-ground or elevated bus system would be wiser), slow (elevated systems are faster to build) and expensive (elevated systems are cheaper to build), and even somewhat dangerous (the city is largely built on a mire).
- Changshui, while certainly a better-looking and more modern airport, has been a headache for pretty much anyone. Wujiaba didn't have nearly as many fog issues and transport to the city centre was convenient. Changshui's metro connection hasn't been finished for years.
- My Chinese colleagues say that everyone knows that tree planting is _the_ preferred way to engage in corruption these days. Something about the fluctuating price and the maintenance costs. I'll ask again tomorrow.
Three massive projects that are expensive, only partially necessary, badly planned and where it's easy to use construction delays and unexpected costs as a smokescreen for a wad of cash here and there.

发布者Large-scale farming is by no means the answer. The burning of trash is usually because there's no adequate trash collection service. The burning of rice stalks is a problem but not because they don't rotate crops (you don't rotate crops with rice afaik). There would be alternatives to rice stalk burning, as below paper suggests:
